Jazz and rock began their courtship in the late 1960s. For a while, it seemed like they would never get together. From the beginning of rock ‘n’ roll in the ‘50s, the two genres had kept their distance from one another, each professing its distaste for the other. Yet despite their initial antipathy, despite their feelings that they had nothing in common, that they would never even be seen together, much less engage in any sort of “hook up” behavior, they eventually fell for each other, formed a union and produced a new breed of musical progeny.
